size of notched trowel for porcelain tiles

[marlb]

Hi,

I am planning to tile the floor and walls of my bathroom. Can anyone advise on the depth of the adhesive for the floor and walls. What size notched trowel should I use for the wall and floor? The tiles are 11mm thick. I have already tanked etc and the adhesive will be BAL maxiflex.

Many thanks

Ask the tile shop or Mfr if the porcelain is suitable to use with a grey adhesive?
Keep the grout joins clean, and clear of adhesive.

I use a 6mm notched steel trowel for just about everything residential. But you can use a 10mm notched trowel on floors if you want a thicker bed of adhesive.

First use the flat edge of the trowel to apply a tight skim coat to the wall or the floor surface, & then comb across it with the notched edge of the trowel - do the same on the back of the porcelain tile (its known as buttering the tile).

FWIW: I comb horizontal on the wall, and comb all the same direction whichever way on the floor.

the size of the notch depends on the size of the tile, essentially the bigger the tile the bigger the trowel, what size are the tiles.
As vinn says 6 and 10mm should cover most eventualities
